MACHINE FOR PASTING AND UNITING SHEETS OF STRAW-BOARD.

SPECIFICATION forming part of Letters Patent No. 453,567, dated June 2, 1891.

Application filed July 5, 1887. Serial No. 243,458. (No model.)

To all whom it 11mg concern.-

Be it known that we, CHARLES SEYBOLD, residing at Cincinnati, in the county of Hamilton and State of Ohio, and CHARLES WHEA- LEN, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Machines for Pasting and Uniting Sheets of Straw-Board, of which the following is a specification.

This invention consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 represents one side of the machine in elevation. Fig. 2 represents the other side of the machine in elevation. Fig. 3 is a front viewof the machine, the feed-rolls, paste-rolls, paste pressure-roll, stationarybar, and movable guide-bar being broken away to show the paste-rolls, pastebrush, &c. Fig. at is a central vertical crosssection of the machine. Fig. 5 is a View of the lower surplus-paste hopper, showing the adjustable spring-fingers thereon. Fig. 6 is a sectional view of one of the pasterolls, the pastetrough, and the paste-regulating roll, also showing the mechanism for adjusting the said paste-regulatin g rolls at anydistance from the paste-rolls to regulate the amount of paste taken up by the paste-rolls. Fig. 7 isa sectional View of the arm and accompanying parts by which the paste-regulating rolls are held in position, the paste-regulating roll being shown with its spur gear. Fig. 8 shows the cam, cam-rods, (the paste-rolls and paste pressurerolls being in dotted lines,) and the mechanism by which the paste pressure-rolls can be regulated, and accompanying parts, through the agency of which the paste pressure-rolls are elevated and depressed on the straw-board sheets. Fig. 9 illustrates the mechanism by which the pressure-rolls are held in position, regulated, and adjusted. Fig. 10 is a detail view of one of the cams.

A represents one side frame of the machine, and B the other side frame. These side frames are castings of any suitable shape or contour, havinglegs A. These side framecastings are connected bythe end castings A 11' are two tables upon which the sheets to be united are laid.

are rcvoluble feedrolls. A are pasting-rolls. B" are revoluble rolls for pressing the sheets onto the pastingrolls when fed forward by the feeding-rolls, as shown in Fig. l, in which L represents the sheets. A are revoluble rolls for pressing together the pasted surfaces of the sheets. The detailed construction of all these parts and the means for operating them will be more fully described hereinafter.

A is the driving-pulley, having secured upon its hub the gear-Wheel a, which imparts motion to the gear-wheels a a the gearwheol a imparting motion to the gear-wheel a the gear-wheel a imparting motion to the gear-wheel of, which imparts motion to gearwheel a the gear-Wheel a also imparting motion to the gear-Wheel a, which imparts motion to the gear-wheel a which latter gearwheels a and o are secured to the shafts of the paste-rollers A A These paste-rolls extend from one side of the machine to the other (extending partly into the paste-trough L,) and one of the paste-rolls has the gearwheel Z) secured on its shaft, which gear-wheel imparts motion to the gear-wheel b, which impartsmotion to one of the intermeshing gears Z2 D which gears 12 b being rigidly attached to the shafts which carry the pressurerolls A A thereby impart motion to said pressure-rolls.

The shafts of the paste pressure-rolls 13*extend across the machine and through the side frames A B. The shaft of one of said press- 85 ure-rolls 3" carries the grooved pulleylf, and the shaft of the other roll B carries the grooved pulley Z)". The shafts B, which carry the pressure-rolls A, have the grooved pulleys (Z and d secured on their ends. A cross-belt B passes over the grooved pulleys b and d and a cross-belt B passes over the grooved pulleys b and d, and thus motion is imparted to the paste pressure-rolls 13*.

One of the shafts B which carry the pressure-rolls A A has the cone-shaped pulley O secured on it, and on the cam-shaft C the cone-shaped pulley O is secured. A belt passing over these pulleys O C imparts motion to the cam-shaft O, and this shaft, carrying the cams O O and O 0*, imparts motion to them. The gear-wheels a a attached to the journals of the feed-rolls O C impart motion to the said feed-rolls 0 O ICO D represents the paste-regulatin g rolls. D represents head-pieces, formed as shown in Figs. 1 and 2. The tops 13 0f the side frame, castings A B are formed with flanges 3, as shown in Figs. 1 and 2. The head-pieces D rest on these top parts 13 of the castings A B at each side, forming between them the recesses D (See Fig. 9.) In these recesses 'D are placed the journal-boxes D which carry the pressure-rolls A and the bearingblocks D Pins D secured at the bottom by nuts d connect the head-pieces D to the top parts B of the side castings A B. Interposed between the lugs d (which are cast on the back of the bearing-pieces D and the bearing-strips d are the springs E. Short screw-threaded rods 6, (see Figs. 2 and 9,) which enter recesses in the journal-boxes D carry the jam-nuts e e. (See Figs. 2 and 9.) By turning these jam-nuts in the proper direction the journal-boxes D carrying. the

pressure-ro1ls'A ,-are either worked inward or outward in the recesses D on the frictionrollerse thus bringing the pressure-rolls A closer together .or farther apart from each other, thus making an adjustment for the thickness of the straw-board that is to pass between them.

The tension of the springs E ordinarily is kept constant for all thicknesses of strawboard, and the strips 01 are not moved by turning the adj Listing-nuts, but the said strips are free to slide in the recesses D and the tension of the springs may be varied by turning the nuts more or less, as desired.

In the shoulders of each of the side framecastings A B (011 each side of the castings) are recesses E, in which recesses slide the journalboxes 6 (two journal-boxes being present in each recess E',) which carry the feed-rolls 0 (See dotted lines, Fig. 1.) Interposed between the twoboxes e in each recess E are the springs 6 and between the upper box 6 and the strip 6 which is at the top of the recess E, are the springs 8. Through the agency'of the screws it these boxes 6 e carrying the feed-rolls 0 C can be brought closer together or moved farther apart from each other. The ends of the screws h are arranged to press upon the ends of the springs, and by turning the screws h in the proper direction the springs 6 in the recesses E press upon the top journal-boxes a moving them downward in the said recesses E, thus bringing the top journal-boxes a an d consequently the top feed-roll O closer to the lower feed-roll. By turning the screws h in the opposite direction said top boxes e are elevated by the springs e thus bringing the top feed-roll farther away from the lower feed-roll, thus making the feed-rolls 0'' ad justable to adapt them to feed sheets of strawboard of various thicknesses.

Above the recesses E in the frame-castings A B on each side of the machine are the recesses E To the sliding blocks 8 at each side of the machine are secured the angular bars E Preferably the bars E are rigidly attached to said sliding blocks 5. These sliding blocks 8 work up and down in said recesses E and the cam-rods E are connected to said blocks 8. Consequently when the cam-rods E are in motion they carry these blocks 8 up and down in said recesses E and the bars E being rigidly connected to said blocks 8 the-said bars move up and down with L said blocks. Through the eyes 71 (which eyes are rigidly connected to the sliding blocks .9) pass the ends of the cam-rods E Interposed between these eyes 72. and nuts 71, on the ends of the cam-rods E are the springs it, and below the eyes IL2 on said cam-rods E are the nuts h These nuts on the cam-rods E can be turned so as to raise or lower the sliding boxes 3, thus raising and lowering the angular gagebars E thus making said gage-bars adjustable. When the cam-rods E work up and down by reason of the finger K traveling either the raised or the drop surface of the cams C the angular gage-bars E are worked up and down, bringing said bars on and ofi the sheets that have just been fed into the machine. The object of these gage-bars E is to hold the sheets being fed to the machine until the sheets fed before them have passed such a point on their journey through the machine that these sheets which are being held by the gage-bars E will not conflict with or overtake the sheets fed before them. The

sheets are carried into the machine by the feed-rolls and are stopped simultaneously by the gage-bars, ready to be received by the pasting mechanism to which the sheets are next fed simultaneously, when they are released by the gage-bars E thus avoiding confusion, making it possible to have a sheet always ready for the pasting mechanism, thus causing no loss of time and gaging the time when the last sheets fed should be released to finish their journey through the machine. In these same recesses E (just above described) are the blocks j. The arms 7t (see Figs. 4 and (3) are connected at one end to the pins 4, which are journaled in the blocks j. The paste-regulating rolls D have their spindles journaled in the free ends of said arms 7c. Adj Listing-arms 7e are secured to the other ends of the pins 4.

The letter 70 represents two adjustmentscrews. (See more particularly Figs. 6 and 7.) These screws impinge against the adjustment-arms 7.0, and turning the said screws (which are supported by and pass through the lugs 75) in the proper direction by their heads k raises or lowers the said adj ustmentarms 70, and through them and the arms 70 the paste-regulating rolls D, (which rolls are supported by said arms 7a,) thus making the paste-regulating rolls D adjustable and allowing more or less paste to be fed to the pasterolls A This adjustment mechanism is shown in detail in Figs. 6 and 7, and the dotted lines show the position the parts may be made to assume.

F represents removable adjustable j ournalbearing pieces for the paste pressure-rollers B (on each side of the machine,) having the slotted arms Z. These journal-bearing pieces F are pivoted on the extended journals of the paste-rolls A and are held in position in any suitable manner. The preferred way is as follows: Through the slotted armsZ pass set-screws Z through the agency of which and the arms Z the journal-bearing pieces F can be adjusted to bring the paste pressurerolls B in the proper plane or angle to the paste-rolls A The paste press ure-rolls B are journaled in boxes Z, which work in the slots Z (See Fig. 8.) Between the j ournal-boxes Z and the top of the journal-bearing pieces F are interposed the springs Z (See Fig. 8.) Short screw-threaded rods Z, carrying two jamnuts Z, are interposed between the journalboXes Z and the bottom part of the journalbearing pieces F. (See particularly Fig. 8.) These rods Z" also enter recesses Z in the bottom part of the j ournal-bearing pieces F. (See Fig. 8.) By screwing the jam-nuts Z in the properdirection the journal-boxes Z, earrying the paste pressure-rolls B are either brought downward in the slots Z bringing the rolls B closer to the paste-rolls A or moved upward in the said slots Z and bringing the rolls B farther away from the pasterolls A, thus regulating the amount of pressure required against the paste-rolls and regulating the distance between the paste-rolls A and the paste pressure-rolls B" to accommodate sheets of straw-board of varying thicknesses.

F represents camrods, which rods are united at the top by yokes F connected to the cam-rods F in any suitable manner. These yokes F pass over the outside of the journal-bearing pieces F and into suitable recesses in the j ournal-boxes Z, so that the boxes Z practically rest on said yokes F so that when the cam-rods F and the yokes F are elevated the journal-boxes Z, carrying the paste pressure-rolls B, are also elevated, and when the said rods and yoke drop, the rolls B also fall back into their original position, the springs Z assisting.

The mechanism just described is illustrated in detail in Fig. 8. The rolls'D have the spurgear 2, (see Fig. 7,) the paste-rolls A also having the spur-gear t. (See Fig. 3.) This sp urgear t meshes with the spur-geart on the rolls D, and thus motion is imparted to the said paste-regulating rollers D.

G and G represent the surplus-paste hoppers, G representing the upper hoppers and G the lower hoppers, the lower hoppers G resting in the brackets G (see Fig. 2,) and the upper hoppers G resting in the brackets G The upper hoppers G are also supported and held in position by the springs G (See Fig. 2.) These hoppers are removable. The upper hoppers G have each a rigid lip m, (see Fig. 4,) and the lower hoppers G a series of flexible fingers on". (See Fig. 5.) These fingers m are preferably provided with the slots m in order to make them adjustable, so that their ends will all be in the same plane. These hoppers G and G receive all the paste which is scraped off the pressure-rolls A by the lips m removing the greater part, and fingers m acting as followers to scrape off all that remains. The paste that is thus scraped off the pressure-rolls A is the paste which is squeezed out from between the two sheets of strawboard while said sheets are passing between said pressure-rolls to be united.

11 represent stationarybars, over which the angular gage-bars E fit and work. These bars H extend entirely across the machine, being rigidly fastened in each side. These bars H, which keep the sheets from buckling and keep them in their proper path, and angular gage-bars E are shown in dotted lines in Fig. 1. The brushes H (see Figs. 8 and 4) extend entirely across the machine. The purpose of these brushes is to assist in spreading the paste evenly over the straw-board sheets passing through the machine and to sweep off the surplus paste.

The fingers H are placed at intervals across the machine and assistin keeping the strawboard sheets in their proper paths. (See Fig. 4:.)

The letters 11 represent guide-strips placed at intervals across the machine to guide the straw-board sheets in as far as the paste-rolls A". These strips H are fastened at '12 (see Fig. 4) to the under side of the tables II and pass between the feed-rolls in over the paste-regulating rolls D and up to the paste-rolls A*. (See Fig. 4C.) The lower feed-rolls C, where these gage-strips H pass over them, are cut away to allow said guide-strips to pass. A table H is provided at each end of the maehine,and is supported by the brackets H. The straw-board sheets rest on these tables and are fed into the machine therefrom. The cams G and 0 each contain the grooves u, (see Fig. 10,) and have each the drop-surface n incline n and raised portion a (See Figs. 8 and 10.) The cam-rods E and F are shaped as shown, and at their lower ends, which slide in the grooves n, form a U-shaped portion provided with the fingers K, which fingers travel the faces of the cams. The fingers K are wider than the cam-rods and extend across the face of the cams, so that the rods may be actuated by the cams.

Between strips K and the bottom of the U-shaped portion of the eam-rods are placed the springs K These springs assist in throwing the fingers K into the drop-surface of the cams. hen the finger K on the cam-rods F is traveling the raised surface of the cam 0 the paste pressure-rollers B are depressed and in contact with the straw-board sheet, and when traveling the dropsurface n the rolls are elevated. \Vhen depressed, the said rolls 13* press the sheets on the paste-rollers A, and when up allow the next sheet to enter between them and said paste-rolls. )Vhen the finger K on the rods E is traveling the raised surface of the cams C the angular gage-bar E is depressed on the sheets, and when traveling the drop-surface 1 3, the said bar E is elevated, allowing the sheets to pass inward ready for the paste-rolls and paste pressurerolls. The cam-rods E come down first, and

are followed by the cam-rods F the cam-rods E by their movements forcing the gage-bar E to impinge against the sheets and hold said sheets ready to deliver them to the paste-rolls I cam-rods F. The cam-rods E, as they oper-- ate thegage-bar E must necessarily come down first to hold the seat ready to deliver it to the paste-rolls .and paste pressure-rolls.

The object of having the gage-bar Ei'which is operated by the cam-rods -E ,.is to guide the sheetsmainly, however, to make it possiblefor the operator to feed in the sheets quickly, the gage-barE of course holding the sheets in readiness to deliver them when the sheets previously fed have passed .between the paste-rolls and paste pressure-rollsthat' is, when the paste pressure-rolls are elevated by the cam-rods F.
